NVME-SNDK-VS-TEMP(1) NVMe Manual NVME-SNDK-VS-TEMP(1)

NAME

nvme-sndk-vs-temperature-stats - Display temperature-related statistics

SYNOPSIS

nvme [<global-options>] sndk vs-temperature-stats <device>

DESCRIPTION

For the NVMe device given, displays temperature statistics.

The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0).

This will only work on Sandisk devices supporting this feature. Results for any other device are undefined.

Expected status and description :-

Statistic Description
The current composite temperature device temperature
Warning Composite TEMPerature threshold temp of overheating
Critical Composite TEMPerature threshold temp of critical overheating
Device Initiated Thermal Throttling support status 0 = unsupported, 1 = supported
Host Controlled Thermal Management support 0 = unsupported, 1 = supported
Thermal Management Temperature 1 (Light throttle) temp to start light throttle
Thermal Management Temperature 1 Transition Counter # times switched into light throttle
Thermal Management Temperature 1 Total Time # seconds spent in light throttle
Thermal Management Temperature 2 (Heavy throttle) temp to start heavy throttle
Thermal Management Temperature 2 Transition Counter # times switched into heavy throttle
Thermal Management Temperature 2 Total Time # seconds spent in heavy throttle
Thermal Shutdown Threshold temp of device shutdown

On success it returns 0, error code otherwise.

OPTIONS

GLOBAL OPTIONS

The following options are defined at the top-level nvme command and are available to this subcommand:

--dry-run

Print the command that would be executed, but do not actually execute it.

--no-ioctl-probing

Disable probing for 64-bit IOCTL support.

--no-retries

Disable retry logic on transient errors.

-o <fmt>, --output-format=<fmt>

Set the reporting format to normal, tabular, 'json, or binary. Only one output format may be used at a time.

--output-format-version=<version>

Select the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names.

--timeout=<ms>

Set the timeout for the command in milliseconds.

-v, --verbose

Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file.

EXAMPLES
